BENJAMIN D. STEVENS, OF BURLINGTON, VERMONT,ASSIGNOB OF ONE- HALE TO T. S. BECK, OF SAME PLACE.

BLIND, SHUTTER, OR SCREEN.

SPECIFICATION forming part of Letters Patent No. 333,565, dated January 5. 1886.

Application filed October 31, 1885. Serial No. 181,496. (No model.)

.To all whom, it may concern:

Be it known that I, BENJAMIN D. STEVENS,

of Burlington, in the county of Chittenden' and State of Vermont, have invented certain new and useful Improvements in Blinds, Shutters, or Screens, of which the following is a specication.

My invention has reference to blinds, shut ters, or screens. and more particularly to sliding devices of this character.

The main object of the invention is to provide the blind with means which will permit it to be easily tted to and removed from the window or other frame in which it is to slide. I also use the same means to serve as aspringpad to hold the blind in the position to which it may be raised or lowered.

In the accompanying drawings, Figure 1 is a front view of the blind and the frame in which it slides. Fig. 2 is a perspective View of the blind, looking at that end or edge to which the spring-holders are attached.

A is the Window or other frame, and B is the blind, arranged to slide therein. On the interior opposite sides of the frame are the vertical guide-ribs a, which may be of halfround or other approved crosssection. On one edge the blind is grooved, as at b, to iit the adjoining guide-rib. On the opposite edge, however, instead ofa groove, such as b, it has a shoulder or ledge, c, to lit against one side of the adjoining guide-rib a on the frame.

To hold the blind in place, there must mani- -festly be some device on the blind to fit against the opposite side ofthe guide-rib a in question. This device consists of the springholder C. There are two of these holders shown in the drawings, mounted on the blind near its top and bottom, respectively. Each holder consists of a spring-strip, d, mounted in a recess, c, in the edge of the blind, and provided with a laterally-projecting tin or rib, f, the set of the spring being such that the iin normallyis maintained in such a positionthat it will iit against rib a on the side opposite that against which the shoulder or ledge c iits. Thus the guide-rib a is embraced between the shoulder or ledge c and the iinsf, and consequently the blind is held in place in the frame while at the same time it can slide up and down.

To remove the blind, all that is needed is to press back the spring-holders far enough to remove the fins f from the rib a, after which the blind can readily be taken out. The recesses c are so shaped as to permit the backward movement of the spring-holding strips, and said strips at their outer ends are provided with handles or heads g,to permit them to be readily manipulated whenever desired.

I prefer to use the spring-holders also as pads by which the blind can be heldin the position to which it may be moved. For this purpose the spring-strips are so shaped that their outer faces,d,bear against the rib a with yielding pressure suficient to hold the blind in place, without, however` offering material opposition to its movement up or down by hand.

Having now described my improvement and the best way known to me of carrying the same into effect, what I claim, and desire to secure by Letters Patent, is-

1. The blind-receiving frame and the sliding blind having on one edgealedge or shoulder, in combination with the retraetible spring-holder carried by the blind and pro` vided with a projecting fin, between which and the said ledge or shoulder the guide-rib or the adjoining face of the frame is received, substantially as and for the purposes hereinbefore set forth.

2. The retractible spring-holder having a projecting iin, and also a face adapted to bear with yielding pressure against the guiderib on the frame, in combination with the sliding blind provided on the edge on which the holder is located with a ledge or shoulder, and the blind-receiving frame, substantially as hereinbefore set forth.

3. The blind-receiving frame, in combination with the sliding blind having on one edge a ledge or shoulder, c, and the retractible spring-holders O, mounted in recesses in the blind and formed or provided with dus f and pressure-faces d', as and for the purposes hereinbefore set forth.

In testimony whereofv I have hereunto set my hand this 26th day of October, 1885.

BENJAMIN D. STEVENS.
